About
Astrix Security is a San Francisco and Tel Aviv-based non-human identity (NHI) and AI security company — founded in 2021 by Alon Jackson (CEO) and Idan Gour — protecting enterprises against the explosion of machine identities, API credentials, service accounts, OAuth tokens, AI agent identities, and CI/CD pipeline secrets that have become the primary attack surface for modern cloud breaches. The company raised a $45 million Series B funding round led by Menlo Ventures through their Anthology Fund (a strategic fund in partnership with Anthropic, connecting Astrix to the AI security ecosystem), alongside Workday Ventures and existing investors Bessemer Venture Partners (BVP), CRV, and F2 Venture Capital — bringing total funding to $85 million. Astrix's non-human identity security platform discovers, assesses, and remediates every non-human identity in an organization's cloud environment: API keys embedded in GitHub repositories, service account credentials with excessive permissions in AWS/GCP/Azure, OAuth app authorizations granted by employees to third-party SaaS tools, and AI agent identities (the new credential type created when enterprises deploy autonomous AI agents that need API access to business systems). As enterprises deploy AI agents that autonomously access Salesforce, Slack, Google Workspace, and internal APIs, the number of non-human identities per organization is growing 10-50x faster than human identities — creating a security gap that traditional identity and access management (IAM) tools built for human users cannot address.

About
Grok is the AI assistant developed by xAI, Elon Musk's AI company founded in 2023, and distributed primarily through X (formerly Twitter). Grok launched in November 2023 as an X Premium perk, with the notable differentiator of real-time access to X posts and a less restricted, more direct conversational style. Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
